‘Sometimes inspiration for big ideas comes from really unexpected places’
Centrifuges are a basic component of any modern medical laboratory. Used to separate different types of cells within a blood sample by spinning them extremely quickly, they are an essential tool for detecting many diseases. Due to the price of equipment and a lack of electricity, however, many medical centres in resource-poor areas lack access to the technology. After seeing this problem first-hand on a visit to Uganda, Manu Prakash, professor of bioengineering at Stanford University, thought up a new tool that wouldn’t require any electricity whatsoever. Inspired by a children’s toy known as the whirligig, Prakash invented the ‘paperfuge’, a hand-powered centrifuge that costs just 20 cents each to produce.
